Device for coating tunnel walls
Description
The invention relates to an apparatus for coating the
inner surface of a tunnel section, to a vehicle, to a
method of coating the inner surface of a tunnel section
and to the use of the apparatus.
In order to secure the rock of a tunnel void, in order
to form a lining layer and also for insulation
purposes, a sprayed concrete layer is normally applied
to the inner wall of a tunnel under construction. In
this case, a tunnel void is understood to mean the free
space which is broken out of a rock by blasting or
cutting. The length of the void in this case depends,
inter alia, on the quality of the stone.
Conventional
void lengths in tunnel and gallery construction lie
between 1 and 6 metres.
Equipment for spraying concrete is known which is used
both in tunnel and gallery construction and also for
securing excavations and embankments. One known item
of equipment has a spraying robot which is constructed
on a carrying vehicle and which is used substantially
to mechanize the guidance of the spray nozzle used for
spraying the concrete as the sprayed concrete is
applied to the surface to be treated and, as a result,
to improve the working safety and the working
conditions for the construction workers.
An item of equipment of this type preferably has a
carrying arm which can move horizontally and vertically
and a spray nozzle which is fixed to the latter, can be
extended and can likewise move freely and which, at its
one end, carries a spray nozzle connected to a concrete
delivery line and used for spraying the concrete. The
said nozzle is in this case fixed to a rotary head
which can be moved about the axis of the sbray

CA 02560089 2006-09-15
COC-0540 - 2 -
so that the axis of the concrete jet emerging from the
spray nozzle can always be kept at an optimum angle
with respect to the surface during the spraying
process. The
control of all the movable elements of
the spraying robot is carried out with a remote
control, it being possible for routine movements, such
as the horizontal movement of the spray lance, to be
automated.
Various properties of a concrete layer applied to the
inner surface of a tunnel or gallery, such as the
compressive strength and the adhesive properties, for
example, depend to a great extent on the spraying angle
and the spraying distance. It is
known that optimum
coating is carried out when the distance of the spray
nozzle from the wall - depending on the type of stone -
is preferably 1 to 2 metres and the axis of the
concrete jet emerging from the spray nozzle is as
perpendicular as possible to the tunnel wall. If these
method parameters are not maintained, the proportion of
material which bounces back is disproportionately high.
In this case, material which bounces back is understood
to mean that quantity of sprayed material which does
not remain adhering to the wall and is therefore left
unused. As a result of sprayed concrete bouncing back,
in addition to the costs for the sprayed concrete which
cannot be used, higher operating costs arise, caused by
material wear and material disposal. Added to this is
the fact that, if the aforementioned method parameters
are not maintained, the amount of concrete actually
remaining on the inner wall of the tunnel after a
spraying process can no longer be determined because of
the amount of material which has bounced back, which
can be determined only in a complicated manner and is
therefore normally unknown.
A tunnel wall to be coated with sprayed concrete
generally has a very irregular composition. A
substantial disadvantage of the equipment described

CA 02560089 2006-09-15
COC-0540 - 3 -
above therefore consists in the fact that it is not
always simple to align the spray nozzle exactly
perpendicular to the surface of the rock and to
maintain an ideal distance from the latter.
Furthermore, the wall thickness of a concrete layer
applied with the known equipment can no longer be
determined, because of the normally irregular tunnel
wall and the material wear which, under certain
circumstances, is high.
Finally, the control of the spray lance and the optimum
adjustment of the rotary head require relatively many
cumbersome and time-consuming operations, which in
practical terms can be carried out only with the
cooperation of at least one person.
US-B-5,851,580 describes a method in which the
application of the sprayed concrete to the surface of
the tunnel is monitored by an automatic control system.
An automatic control system of this type necessitates
complicated technology, so that the corresponding
coating apparatus is complicated and therefore
uneconomic. This can be attributed, inter alia, to the
fact that appropriate apparatuses generally have a high
number of joints (at least 7) and all the joints have
to be provided with measuring systems and controllers.
It is an object of the present invention to provide an
apparatus for coating inner surfaces of tunnels with
which sprayed concrete can be applied uniformly and
with little loss of material, the intention being for
the apparatus to be economical to purchase and to
operate.
The achievement of this object is based on an apparatus
for coating the inner surface of a tunnel section with
sprayed concrete comprising
a) a spray nozzle,

CA 02560089 2006-09-15
COC-0540 - 4 -
b) a spray lance at whose one end the spray nozzle a)
is arranged,
c) a carrier, on which the spray lance b) is fixed
and
d) a connection point for a connecting line for the
delivery of sprayed concrete, which is preferably
located on the spray nozzle a),
it being possible for the spray lance b) and the spray
nozzle a) in each case to be moved by means of joints.
The achievement of this object according to the
invention is characterized in that there are
e) a joint which connects the carrier c) and the
spray lance b) to each other and mounts the spray
lance b) in such a way that the spray lance b) can
be moved in rotation about the vertical axis,
f) a joint via which a segment of the spray lance b)
that faces the spray nozzle a) can be raised
upwards and lowered downwards,
g) a joint via which the segment of the spray lance
b) that faces the spray nozzle a) can be
lengthened or shortened telescopically,
h) a joint via which the spray nozzle a) can be moved
in rotation about the longitudinal axis of the
segment of the spray lance that faces the spray
nozzle a), and
i) a joint via which the spray nozzle a) can be moved
in such a way that the outlet opening of the spray
nozzle a) can be brought close to or away from the

ak 0256(089 2011-12-07
-5-
longitudinal axis of the segment of the spray
lance b) that faces the spray nozzle a),
a first control device, with which the movement of the spray
lance b) can be directed via the joints e), f) and g), and a
second control device, with which the movements of the spray
nozzle a) can be directed via the joints h) and i), are
provided.
According to the definition, a tunnel section is also to be
understood to mean the section of a cavity which is not
referred to as a tunnel in normal everyday language, for
example a mine or an excavation.
It is important that the first control device and the second
control device operate independently of each other or can be
operated independently of each other. However, it is possible
for the first control device and the second control device to
be arranged beside each other on a common operating device.
It is advantageous that the apparatus according to the
invention has only five joints and, as a result, can be
controlled relatively easily. This low number of joints also
necessitates a comparatively simple construction, as a result
of which the spraying apparatus according to the invention
becomes particularly economic. The assignment according to
the invention of the joints to two control devices that
operate separately from each other ensures an ability to be
operated comparatively easily. In spite of this ability to be
operated easily and the high economy, the apparatus according
to the invention ensures a uniform application of the sprayed
concrete, specifically with a low loss of material.
In a preferred embodiment of the invention, the first control
device and the second control device can in each case be
operated manually, without computer assistance, with

ak 02560089 2011-12-07
-6-
the aid of two joysticks, one joystick belonging exclusively
to the first control device and the other joystick belonging
exclusively to the second control device. The two joysticks
are expediently arranged on a common operating device, such
as a remote control device.
As a result of dispensing with the computer assistance, this
embodiment of the invention ensures a low purchase price of
the apparatus according to the invention. However, because of
the low number of joints and the control system according to
the invention, the ability to be operated comparatively
easily is provided in spite of the lack of computer
assistance.
In a further preferred embodiment of the invention, the first
control device is computer-operated and the second control
device can be directed manually, without computer assistance,
with the aid of a joystick. This variant ensures the ability
to be operated even more simply as compared with the
embodiment described previously.
The segment of the spray lance b) that faces the spray nozzle
a) or at least one section of the segment of the spray lance
b) that faces the spray nozzle a) is expediently formed as a
telescopic arm.
A segment of the spray lance b) that faces away from the
spray nozzle a) can preferably be extended in the direction
of the spray nozzle a) , so that, by means of appropriate
extension and retraction, the distance between carrier c) and
spray nozzle a) can be varied, provision being made that,
during operation, the segment of the spray lance b) that
faces away from the spray nozzle a) is fixed in an extended
position and, during transport and parking, the segment of
the spray lance b) that faces away from the spray nozzle a)
is fixed in a correspondingly retracted position, in which
the distance between carrier c) and spray nozzle a) is

CA 02560089 2006-09-15
000-0540 - 7 -
relatively small. This
ensures that the apparatus
according to the invention can be transported easily
and needs a comparatively small parking space. In
addition, this technique makes it possible for there to
be a large distance between spray nozzle a) and carrier
during operation.
As a rule, the apparatus according to the invention is
arranged on a mobile chassis. This can be located, for
example, on a heavy goods vehicle. The
present
invention thus also relates to a vehicle, preferably
present as a heavy goods vehicle, which has the
apparatus described above.
Furthermore, the invention relates to a method of
coating the inner surface of a tunnel section with
sprayed concrete with the aid of the apparatus
described above, the spray nozzle being kept at a
distance of 1 to 3 metres at right angles to the inner
wall of the tunnel during the spraying process. This
ensures that the proportion of material bouncing back
is relatively low and the application is carried out
uniformly.
Finally, the invention also relates to the use of an
apparatus described above for the production of
coatings in tunnel and mine construction.
In the following text, the invention will be explained
in more detail using the drawing, in which:
Figure 1 shows an illustration which illustrates the
basic construction and the mechanical
functional principle of an apparatus
according to the invention in a cross-
sectional view and in an oblique view,
Figure 2a shows a cross-sectional depiction of a
vehicle according to the invention, which

CA 02560089 2012-01-18
-8-
illustrates the functioning of the apparatus
according to the invention schematically,
Figure 2b shows a depiction in the form of a plan view
which illustrates the functioning of the
apparatus according to the invention, and
Figure 3 shows a schematic diagram of an operating
device for the operation of the apparatus
according to the invention, in which both the
first control device and the second control device
can be directed manually without computer
assistance.
The apparatus according to the invention shown in Figure 1
has, in the lower region, a carrier 1, which is connected
via feet 3 to a mobile chassis 2, not illustrated in Figure
1. In the upper region, the carrier 1 is connected via a
joint to the spray lance 4, wherein the spray lance 4 is
mounted on turret 11. Turret 11 together with spray lance 4
being mounted by means of the joint 5 in such a way, that
the spray lance 4 (including items 8, 12, 14, 13, 9, 15, 16,
17, 18, 19 and 7) can be moved in rotation about the
vertical axis 6.
The spray lance 4 arranged above the
carrier 1 has, at one end, a spray nozzle 7 and is divided
into a segment 8 that faces away from the spray nozzle 7 and
into a segment 9 that faces the spray nozzle 7. The entire
spray lance 4 is connected to the upper, rotatable region of
the carrier 1 (rotary head 11) via a joint 12 in such a
way that the segment 9 of the spray lance 4 that faces the
spray nozzle 7 can be raised upwards and lowered downwards.
The segment 9 of the spray lance 4 that faces the spray
nozzle 7 is partly formed as a telescopic arm 13, so that
the segment 9 of the spray lance 4 that faces the spray
nozzle 7 can be lengthened or shortened telescopically
via the joint 14.
The segment 8 of the spray lance 4
that faces away from the spray nozzle 7 can be extended
in the direction of the spray nozzle 7, so that, by means
of appropriate extension and retraction,

ak 02560089 2011-12-07
-9-
the distance between carrier 1 and spray nozzle 7 can be
varied. The
joints 5, 12 and 14 can in each case be
equipped with a distance measuring system, which
contribute to the semiautomatic control. Provision is
made is that, during operation, the segment 8 of the
spray lance 4 that faces away from the spray nozzle 7 is
fixed in an extended position and, during transport and
parking, the segment 8 of the spray lance 4 that faces
away from the spray nozzle 7 is fixed in a
correspondingly retracted position, in which the distance
between carrier 1 and spray nozzle 7 is comparatively
small. The apparatus shown in Figure 1 is in this parking
position. The spray nozzle 7 is connected to the end of
the telescopic arm 13 via a joint 16 at the fixing point
of the spray head (TCP) 15. Via this joint 16, the spray
nozzle 7 can be moved in rotation about the longitudinal
axis 17 of the segment 9 of the spray lance 4 that faces
the spray nozzle 7 between this joint 16 and the spray
nozzle 7 there is a further joint 19, via which the spray
nozzle 7 can be moved in such a way that the outlet
opening 18 of the spray nozzle 7 can be brought close to
or away from the longitudinal axis 17 of the segment 9 of
the spray lance 4 that faces the spray nozzle 7. On the
spray nozzle 7 there is a connection point, not shown,
for a connecting line for the delivery of sprayed
concrete.
Figure 2 shows an apparatus according to the invention
which is mounted on a special heavy goods vehicle. The
spray lance 4 is in the extended state (operating
position). Because of the high torque which is caused by
the extended spray lance 4, the vehicle has special
supports which can be extended for securing support
before and during operation.
Figure 2a shows, schematically, the movements of the
spray lance 4 which have to be carried out in order

ak 02560089 2011-12-07
-10-
to guide the spray nozzle 7 along the inner wall of the
tunnel in the plane which is formed by the vertical and the
longitudinal axis 17 of the vehicle. These movements of the
spray lance 4 may be controlled exclusively by the joints 12
and 14, by the angle of the spray lance 4 with respect to the
vertical being varied via the joint 12 and, via the joint 16,
by varying the length of the segment 9 of the spray lance 4
that faces the spray nozzle 7, the
desired distance from
the inner surface of the tunnel being maintained. If the
spray nozzle 7 is to be moved out of the aforementioned
plane, the "rotary tower" 11 must be moved via the joint 5.
The movements which the spray nozzle 7 completes along the
arrows shown in Figure 2a are thus controlled exclusively via
the joints 12 and 14.
Figure 2b illustrates how the spray nozzle 7 is guided at a
constant distance along the inner surface of the tunnel in a
plane which is formed by the longitudinal axis 17 of the
vehicle and the horizontal. Movements which the spray lance 4
completes parallel to the longitudinal axis 17 of the vehicle
and in the last-named plane - in accordance with the arrows
shown in Figure 2b - are controlled exclusively via the
joints 5 and 14. For these movements, only the joints 5 and
14 are thus actuated, the angle with respect to the
longitudinal axis 17 of the vehicle being varied via the
joint 5, and the length of the segment 9 of the spray lance 4
that faces the spray nozzle 7 being varied via the joint 14
in such a way that a constant distance from the inner surface
of the tunnel is approximately maintained. Movements which
are completed out of this plane are controlled via the joint
12.
Via the joints 16 and 19, the outlet opening 13 of the spray
nozzle 7 is kept perpendicular to the inner surface of the
tunnel during operation.

ak 02560089 2011-12-07
-11-
The remote control device, illustrated in Figure 3, of an
apparatus according to the invention shows a large joystick
20 for the control of the movements of the spray lance 4 via
the joints 5, 12 and 14, a small joystick 21 for the control
of the spray nozzle 7 via the joints 16 and 19, a control key
22 for the supply of sprayed concrete, a control key 23 for
changing over the operating mode from semiautomatic to
manual, a control key 24 for extending and retracting the
part segment of the spray lance 4 that faces away from the
spray nozzle 7, in order to set the parking and operating
position of the apparatus according to the invention,
a
control key 25 with which, in computer-assisted operation,
movement sequences of the TCP 15 (fixing point of the spray
head) can be stored or pre-programmed (see below), and a
rocker 26, with which the execution of the stored or pre-
programmed movements can be controlled in computer-assisted
operation.
In the operating mode "manual operation without computer
assistance", computer and distance measuring system are not
active. The two joysticks drive valve boosters of hydraulic
valves directly.
The movement predefinitions by means of the large joystick 20
are then as follows:
Lever to right/left = joint 5; rotate to right/left
Lever to front/rear = joint 12; raise/lower the
segment 9 of the spray lance 4 that faces the spray nozzle 7
Rocker 26 up/down = not effective - no movement
pre-definition is made

ak 02560089 2011-12-07
-12-
The movement pre-definitions by means of the small joystick
21 are as follows:
Lever to right/left = joint 16; rotate spray nozzle
7 to right/left
Lever to front/rear = joint 19; tilt spray nozzle 7
forward/back
During manual operation with computer assistance
(semiautomatic operation), the computer and the distance
measuring systems in the joints 5, 12 and 14 come into use.
With the aid of the rocker 26, the movements of the TPC 15 in
computer-assisted operation are predefined as follows:
Rocker up/down = TPC is moved forward/backwards in accordance
with the arrows illustrated in Figs 2a, 2b.
The computer assistance ensures that the TCP 15 is guided in
parallel with a "teach-in" straight line defined in space.
The TCP 15 completes a linear movement along a previously
defined straight line, which can be in accordance with the
arrows in Figure 2a and 2b. The straight line is defined by
the operator in a "teach-in mode" by means of moving to the
first and last points of the straight line. This is done by
the operator moving manually to the first point, which is
defined by the spatial coordinates xl, yl, zl, and causing
this to be registered by pressing a knob. At another point in
space, a second point x2, y2, z2 is moved to and registered
in the same way. The above-described storage of a straight
line, specifically by programming in a first and second
point, is carried out with the aid of the control key 25. If
the rocker 26 of the large joystick 20 is moved, then the TCP
15 is moved forwards and backwards accordingly, specifically
along the previously defined straight line. All other
parallel straight lines are then selected by means of

ak 02560089 2011-12-07
-13-
the large joystick 20. Care must be taken that that the y
and z coordinates are not simply kept constant when
moving forwards and backwards but that the further
movements are carried out in parallel with the previously
defined straight line. In other words, it is possible to
state that, once the straight line has initially been
determined, the operator can carry out the spraying work
in such a way that the spray lance 4, viewed in three
dimensions, is moved up/down or left/right, the spray
nozzle 7 in the process completing movements parallel to
the previously defined straight lines, which are in
accordance with the arrows in Figures 2a, b.
